Improved ion adsorption capacities and diffusion dynamics in surface anchored MoS⊥MoB and MoS⊥MoBO heterostructures as anodes for alkaline metal-ion batteries.

First-principles calculations were performed to analyze the atomic structures and electrochemical energy storage properties of novel MoS⊥boridene heterostructures by anchoring MoS nanoflakes on MoB and MoBO monolayers. Both thermodynamic and thermal stabilities of each heterostructure were thoroughly evaluated from the obtained binding energies and through first-principles molecular dynamics simulations at room temperature, confirming the high formability of the heterostructures. The electrochemical properties of MoS⊥MoB and MoS⊥MoBO heterostructures were investigated for their potential use as anodes for alkaline metal ion batteries (Li, Na and K).

Predictive Value of Annenxin A1 for Disease Severity and Prognosis in Patients with Community-Acquired Pneumonia.

This prospective, single-center study evaluated the clinical utility of annenxin (Anx)A1 level as a biomarker for determining the severity of illness and predicting the risk of death in hospitalized patients with community-acquired pneumonia (CAP). A total of 105 patients (53 with severe [S]CAP, 52 with non-SCAP) were enrolled from December 2020 to June 2021. Demographic and clinical data were recorded.

Perioperative application of midline catheter and PICC in Patients with gastrointestinal tumors.

Purpose: This study aimed to compare the application value of midline catheter and peripherally inserted central catheter (PICC) in patients with gastrointestinal tumors during the perioperative period.

Methods: 487 patients with gastrointestinal tumors admitted to Qingdao Municipal Hospital from August 2016 to September 2018 were selected and retrospectively analyzed. 279 patients treated with midline catheters during the treatment were regarded as the study group, and another 208 patients treated with PICC were regarded as the control group.
